Abstract: The damper includes a cylindrical housing with a cylindrical passageway formed therewithin. A piston traverses the cylindrical passageway. A monofilament element is integral with the piston on a first end and includes a plurality of molded annular rings on a second end. The molded annular rings serve as a male element for engaging a female clamping element with internal serrations. This allows for the female clamping element to be positioned along an adjustable distance with respect to the male element. The portion of the cylindrical passageway through which the piston traverses when the damper is in its retracted position has a reduced diameter.

Granted: 2003-04-29
Abstract: A multi-spectral two-dimensional imaging spectrometer (10) includes a combination of achromatic, well-corrected lenses (14) for imaging a two- dimensional scene on an internal field stop (20). The light emanating from this intermediate image is collimated with another well-corrected lens (24).  A spectral separation subassembly (22) that divides the incident light into multiple, identical, and independent arms is placed in the collimated space following the collimating lens (24). The light in each arm is spectrally filtered based on the properties of an interference filter (30) in each arm.  An imaging subassembly (32) composed of a well-corrected lens (34) forms contiguous images onto a single two-dimensional detector array (36). The images are identical copies of the original object with each copy having a different spectral component and can be viewed on a standard monitor or alternatively on a computer employing an analog-to-digital conversion device .

Abstract: A process for preparing calcium aluminate from aluminum dross comprising crushing (10) the dross and extracting solubles therefrom with water in a digester (14). The brine so obtained is processed in a crystallizer (32) to obtain fluxing (32 (a)) materials contained therein, and the insolubles are fumaced (22) to separate the free aluminum metal therefrom. To prevent undesirable reactions from occurring in the digester (14) which result in the production of hazardous and noxious products, the pH in the digester is controlled in the range of from about 5 to about 8, by withdrawing a magnesium chloride-containing stream (32 (b)) from the crystallizer (32 (c)) and introducing it into the digester (14).

Title: Generation of voice messages
Inventor: PAGE JULIAN HENRY
IPC: G10L13/04
Filed: 1998-07-31
Granted: 2009-07-21
Abstract: A method of generating a message having an invariable por-tion (U1) and a variable portion (V) is provided. Most of the in-variable portion (U1) is provided in the form of recorded speech (A) whereas the variable portion (V) is provided in the form of syn-thesised speech (B). The synthe-sised speech (8) also extends by half a phoneme into the invari-able portion (U1) of the message.  The synthesised speech (B) and the recorded speech (A) are then con-catenated, with a transition signal being formed on the basis of a boundary portion of each of the recorded (A) and synthesised sig-nals (B) about any join (8). In forming the transition signal, a set of transition signal pitchmarks is created and an overlap-add tech-nique is used to copy the wave-form within the boundary portions of the speech signals (A, B) around the transition signal pitchmarks.  The signal around the penultimate pitchmark in the leading boundary portion is copied to the trailing half of the transition signal and the signal around the second pitchmark in the trailing boundary portion is copied to the leading half of the transition signal. In this way, the characteristics of the generated message around the join (8) change gradually between the characteristics of the recorded speech (A) and the characteristics of the synthesised speech (B).

Title: Method for processing network messages
Inventor: SMART DAVID CHARLES
IPC: H04L29/06
Filed: 2000-02-08
Granted: 2004-04-13
Abstract: A network includes a plurality of electronic control units (ECU) connected with each other and receiving messages via a bus, each message having an identifier portion and a data portion. An ECU processes messages by converting the message identifier to a hash value, comparing the hash value to a plurality of index values stored in a lookup table, the lookup table having relevance values corresponding to each index value, discarding the message if a corresponding relevance value indicates that the message is not relevant to the ECU, inserting the message into memory buffer if a corresponding relevance value indicates that the message is relevant to the ECU, and further processing only selected ones of the messages in the buffer. Preferably, the hash value has fewer data bits than that of the identifier portion of the messages, and the number of unique hash values is the same as a number of index values. The number, N, of index values for the lookup table is determined by selecting from a plurality of potential values for N, a particular N value which minimizes a number of non-relevant messages received by the ECU.

Abstract: L'invention concerne un système de transmission de signaux de commande hydraulique et d'énergie hydraulique vers des outils fond de trou d'un puits, ce système permettant de réduire le nombre de canalisations hydrauliques installées dans le trou de forage. Des signaux de commande hydraulique peuvent être fournis à des pressions relativement basses, la pression hydraulique régnant dans la canalisation pouvant être augmentée de manière sélective pour être portée au-dessus d'un niveau de seuil, afin de fournir une énergie de commande hydraulique. Ce système autorise la constitution de plusieurs trajets de commande à travers un nombre réduit de canalisations hydrauliques, pour permettre la flexibilité et la vérification du fonctionnement des outils fond de trou. Le fonctionnement hydraulique en boucle fermée permet de surveiller le fonctionnement des outils fond de trou, et une combinaison des canalisations hydrauliques sous pression permet d'obtenir un code de fonctionnement destiné à la commande sélective des outils fond de trou. Quatre canalisations hydrauliques peuvent assurer une commande et un fonctionnement indépendants de sept outils fond de trou, des combinaisons supplémentaires pouvant être agencées.

Abstract: Video adapter hardware and software permitting the display of computer information and television signals across several display devices. The video adapter hardware includes two graphics user interface accelerators, two television tuners, one or more video decoders, and one or more video multiplexes. Each accelerator is coupled to a memory unit for access to graphics data. One television tuner accepts input from an outside television source, such as a cable television company or a video cassette recorder. In addition, the video multiplexers accept input from other external video sources. Video data is output from the graphics accelerators to multiple screens. Video adapter software displays a toot window allowing the user to select first input for the first display device and a second input for the second display device. The software displays the results of the two inputs on the respective display devices. If the inputs are identical, however, the information may be displayed across both display devices.
